Create Normal Cut Feature Example (C#)

This example shows how to create a normal cut feature.

//------------------------------------------------------------------------------
// Preconditions:
// 1. Open:
//    c:\Users\Public\Documents\SOLIDWORKS\SOLIDWORKS 2019\samples\whatsnew\sheet metal\normal_cut.sldprt.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Creates Normal Cut1 in the FeatureManager design tree.
// 2. Edits the feature by specifying a normal cut direction entity.
// 3. Inspect the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save any changes to it.
